Book Information: Sorry, Chief...

When the diabolical Dr. X invents a serum capable of making a man invisible and threatens to sell it to KAOS, the fate of the whole world hangs in the balance.

Only one man can jump into the breach against the Forces of Evil--Maxwell Smart, Agent 86 from Control. Max's assignment: to apprehend Dr. X, get the serum and formula, and, most important, bring back alive the six invisible guinea pigs, proof that the serum works. (All right, would you believe...FIVE invisible guinea pigs!)

Does Max succeed in his quest? Does the whole civilized world triumph? Would you believe it?
